To all whom it may concern." v vBe it known that I, FRED WILLIS- GUNN, acitizen of the United States of .America, residing at Dedhain, in thecounty of Norfolk andState of Massachusetts, have invented ;new anduseful Improvements in" Hose-Clamping Tools, of which the following is aspecification. I

This invention relates to tools for applying clamping wires or hands tohose or like flexible tubes for clamping and securing the same to pipes,nozzles, nipples, couplings,

- and the like. 1 A principal object 'ofthe'invention isto provide asimple and easily op- .erated tool thatis adapted to draw up a clampingwire tightly around the hose and then to sever it leaving a properlength of v,the wire endsprojecting .in most advantageous position forbending back to make the clamp secure. A further object is'toprovidea-tool of the kind described equipped with means for severing andremoving easily extremities of the wire that are caught in the deviceafter an operative. -movement thereof. still further objectis to providea wire clamping toolequipped with an op erating element that-is in one.position adapted to cooperate withthe wire for the drawing up thereof-toleave ends'projecting at the required angle, and in'another positionadapted to serve as a cuttin'g ofi instrumentality for removingextremities'of the wire.

The foregoingfandj other objects and "advantages of the invention willmore fully appear .from the following detailed ;descrip- .tion, andthedistinctive features of'novelty will thereafter be nendediclaims; 3 7

This pin hasa-s'quared or angular head 14 atone endthereof adapted to receive awrench or like operatingftool};

and its other end is fitted with a cotter pin- 14", tolhold the same:from casualdisplace nent., This .pin has a:'hole 14 throughith'eintermediate portion thereof and through In use a pipe or nippleP. withthe hose thereon ready .for clamping is provided a clamp wire W which asusual is doubled in termediate its length atW and has its end 75 I whichthe wires tare adapted tolbe'pa ssed.

portions'passed through. this double orloop to be drawnfup and bentbackwas indicated at B for holdingthe clamp in position, In

accordance with my invention, the extremities .W of the wire afterbein'g I passed throughtheloop W are passedth-rough the.

hole 13 of the slab 12: and thence through the h0le14of the pith-I114Therlipon on wrench or handle-inla direction to thefleft .turning jthepin 14 meansof a 'suitable or reverse clockwise, theL-wires aredrawn uptaut so as to clamp the hose 'closelyfand securely to, the pipe and inthis. drawing up operation the wire will-be bent. at alsmall angle onthe corner 13* .ofthe hole 13.," this they are drawn up to the requisitedegree of tautness for clamping, with the wire ex tremities thus leftprojecting outward from the loop W, adapted to hold the hose clamped andin readiness to be pressed back or hammered down as indicated at Btocom-' plete the clamp. Upon the severing of the wires at the point 13the extremities thereof will be Wound around the pin 14 to a greater orless extent as well as'being passed throughv the hole 14. Theseextremities of the wires may now be quickly and easily freed from thepin 14 by swinging the slab 12 so that its cutting edge 12? movesdownward to engage the pin 14: as indicated in Fig. 4, it

' being noted that the dimension of said slab is correctly proportionedfor this purpose.

'The eupo ont ning t e pi to th ight or in a clockwise direction as seenin Fig. 4, the wire ends are severed directly over the hole ll and'arethus disengaged from the pin. I preferably form the other end of the Odyor holder 10 with convex edges 10 similar to the edges 10 and ivotadjacent this end atll" a slab 12 having a hole' 13,

the purpose of this being to permit a hose to be engag'edwith this endof the device for applying the clamping wire in cases where theprojecting ends of the wires are of greater length. i In this casethe'wires will be passed 'throughthe hole' 13' and thence through thehole 14 of the pin andthedeviceo erated otherwise'as already described.

7 I am'aware that the'invention maybe embodied inother specific formswithout departing from ,the spirit or essential attriutes thereof, and Itherefore desire the present embodiment to be considered in all"respects as. illustrative and not restrictive, reference being had tothe appended claims rather than-to the foregoing description to indicatethe'scope of the invention,

Having described my, invention whatI claimas'new and desire to secureLet- 'ters Patent is: 35

1. .A .hos e clamping tool, comprising a in substantial parallelism withthe" pivotal axis of said member spaced from the operaitive 'end'thereofiand adapted ,to engage the extremities of wire for draw ng theam e t- 2. A hose clamping tool, comprising a holderhaving' aslabfpivoted transversely r therein 'adjac'ent one end'thereof, saidslab hav g. a e req ng' P s g efthrough and having one end thereofformed to serve as a cutter, and a ,turning pin e 'ntel in said he derfbs of sai S in presence of'tw'o witnesses;

adapted to engage the wire extremities, to draw the same through thepassage of said slab and cause severance thereof against an edge of thewire receiving passage of said slab, the cutter end of said slab beingthen adapted to serve as a means ,for removing the severed ends.

3. A hose clamplng tool, comprising a 7 body constituting a holderhaving transversely pivoted adjacent one end thereof a slab vwith a wirereceiving passage therethrough at one side of said pivot and having oneend thereof formed with a cutting edge,

and a turning pin mounted in said holder back of said slab with apassage} thercthroughto receive the wire extremities,-said pin equipped,with means for turning the same to draw up the wire and 'finally'qauseseverance thereof byenga'gement with an edge of the wlre receiv ngpassage of sa d slab, said pin being in position'for co-action with thecutting edge "of said slab to sever and remove the detached wire ends.

4. A hose clamping tool, comprising a body constituting a holderwithslabs trans- 1 versely pivoted adjacenteach end thereof, each of'said slabs having a wire receiving passage therethrough at one side ofits pivot,and a turning pin mounted intermediate'the length ofsaidholder adapted to draw up wire extremities from either end "of'saidholder when projected] through ither of said slab passages.

5. A hose clamping tool, comprising a body constituting a holder withslabs transversely pivoted, adjacent each end'thereof each of said slabshaving a wire receiving passage therethrough at one side 'of its pivot,and a turning'pin mounted intermediatethe, length of said holder adaptedto draw up wire extremities from either end of said holder when-'projected through either of'said slab passages, one of said slabshaving an end thereof formed as a cut- I ting edge and adapted tocooperate with 7 said pin for severing and removing detached wire ends.
